The goaltending switch which didn't work out for the Wings: Dom for Cujo

In lieu of the Chicago Blackhawks' decision to walk away from Antti Niemi's arbitration award, Fanhouse's Adam Gretz looked back at the Stanley Cup champions who shifted goaltending duties after winning the Cup, and the results thereof, and one particular move played out ridiculously poorly for the Red Wings:

Prior to the 2001-02 season the Red Wings sent forward Slava
Kozlov -- part of the Russian Five -- and a first-round pick to the
Buffalo Sabres for the legendary Dominik Hasek. He was 36 and coming off
an eight-year stretch that saw him lead the NHL in save percentage six
times. Of course, he made the 2002-03 Red Wings an unstoppable force -- just look at that roster, loaded with future Hall of Famers
-- as they steamrolled their way to a 51-21-10 record regular season
record, before winning 16 of their 23 playoff games and winning a third
Stanley Cup in six years. Hasek announced his retirement after the
season, and was replaced by veteran Curtis Joseph. The Red Wings made
the playoffs the following season, but were swept in the opening round by the Anaheim Ducks. Hasek eventually returned to the NHL -- and the Red Wings -- but was never the same, dominant player he was in his prime.

As it turned out, Cujo came to Detroit with a wonky ankle that limited his lateral mobility throughout his tenure with the Wings, and after he left the Wings, he finally admitted that he left his heart in Toronto, which, in retrospect, any Red Wings fan could tell you was evident in his play.

The other netminding move the Wings made after winning a Cup ended in a more positive result:

UPDATE: I originally missed/forgot about Mike
Vernon and the 1996-97 Detroit Red Wings. Vernon and Chris Osgood both
played for the team that season, with Vernon starting 20 playoff games,
including all 16 Detroit wins. Following the season he was traded to San
Jose for a couple of draft picks. Osgood took over the full-time No. 1
job during the 1997-98 season (and won the Cup) with Kevin Hodson and
Norm Maracle backing him up.
